A better effect with mannitol in the mix LOCAL ANAESTHESIA
DCP study day
An overview of forensic dentistry, protecting vulner- able people, the risks and responsibilities surrounding direct access and an update in infection control were all covered at the latest DCP study day organised by NHS Educa- tion for Scotland. Around 50 DCPs were at Hampden Park on 22 February for the event, which was opened by forensic odontologist Fiona Waddington. Fiona, a GDP at Corsehill
Dental Care in Stewarton, East Ayrshire, discussed the role of the DCP in forensic dentistry and how forensic dentists accurately age an individual. She also looked at how dental identification has been used
Education. Dental care professionals cover a wide range of topics
in mass disasters such as the Boxing Day tsunami of 2004, using images and information from colleagues who were present during the aftermath of the event. She also covered the often-
harrowing subject of bite mark analysis, using her experi- ences and that of colleagues to illustrate cases of domestic violence, child abuse and even murder. Helen Pattinson, consultant in special care dentistry at NHS
Greater Glasgow and Clyde, then took to to the podium to present on ‘Consent/ Incapacity and Protecting Vulnerable Groups’. She talked about the changes in legisla- tion involving incapacity and consent as well as discussing the new Protecting Vulnerable Groups Scheme and how it impacts on DCPs. Claire Renton, dental
advisor with the MDDUS, then talked about the possible risks and responsibilities that direct access will bring to various DCP groups, before Lynne Cotter, infec- tion control support dental nurse at NHS Education for Scotland, gave an update on infection control.
Occlusal society meeting LATEST DEVELOPMENTS
The British Society of Occlusal Studies is holding a summer meeting on 21 and 22 June in Manchester.
The meeting will be titled “The latest in occlusion, orthodontics, TMD and orafacial pain”.
Professor Tara Renton will speak on the first day to provide an update on classifica- tions, diagnosis and research developments of TMD and orafacial pain.
Tara completed a PhD
in trigeminal nerve injury at King’s College London between 1999 and 2003 and has been the chair there since 2006.
Along with the Institute of Psychiatry at KCL and Imperial College, Tara and collabora- tors have established a leading research programme in trigem- inal nerve injury and pain. On day two, Dr Ambrosina Michelotti will discuss the relationship between occlusion, orthodontics and TMD. This will include a critical review of the evidence and
advice on the management of occlusal and orthodontic treat- ment in individuals displaying symptoms of TMD. Ambrosina graduated in dentistry in 1984 and qualified as a specialist in orthodontics in 1991.
Since then, she has taught undergraduate and postgrad- uate courses in orthodontics and TMD at the University of Naples Federico II.
Her research interests are focused on TMD and orthodon- tics and she has published more than 130 papers worldwide.
An improvement may be in order for the most common dental anaesthetic. The inferior alveolar nerve block is the most commonly used form of local anaes- thesia for mandibular restorative and surgical procedures. A study found that the addition of the drug mannitol significantly increases the effectiveness of this anaesthetic. The journal Anaes- thesia Progress presents a study testing the efficacy of lidocaine with epinephrine compared with equal amounts of lidocaine with epineph- rine plus mannitol. After injection of the anaes- thetic, the subjects’ teeth were electric pulp tested for sensation. Pain of solution deposition and postoperative pain were also measured. Failure rates of 10 to 39 per cent for the traditional formulation of lidocaine and epineph- rine have been reported. One reason may be that, because of the perineurial barrier around the nerve, the anaesthetic solution does not completely diffuse into the nerve trunk. With mannitol, the anaesthetic solution permeates the nerve trunk in greater amounts, increasing the efficiency of the anaesthetic.
